Tiff vs. Jpeg

[widdors]

I'm curious how many of you save your photos in Tiff format to reduce the chance of artifacts. Everything I've read says to, but I haven't started to yet. Anyone benefitted from doing so?

It depends on what I'm shooting.

All my model shoots I shoot RAW. I download those and burn to CDROM for backup. Consider those digital negatives. I then do all my editing in PSCS2 and save in tif format @300 dpi. Those are the masters. Finally I convert those into jpeg resizing to 600x4x0, 8bit, sRGB. Those are for the models online portfolio and posting on web sites.

For sports and general photography I shoot jpeg fine. Those stay as jpeg for me. I suppose I could convert to tiff for archiving, but it just doesn't make sense to me.

We just had a girl speak at our PPC meeting on Monday about photoshop and such, and she said to definitely save in tiff as opposed to jpeg to eliminate the artifacts issue. Only save to jpeg if you are sending them in an email or putting them on a website.

My opinion on the issue:
If you shoot in jpeg and don't edit the file, it makes no sense to convert to tiff.
If you edit the jpeg file, then saving in tiff is most likely the best solution.
If you shoot in RAW or tif, then saving in tiff is absolutely the right thing to do.

Yeah, I'm sure you are right about this. I shoot in raw, so I never really thought about it from shooting in jpeg point of view.

What about printing at places like costco or wolf camera. I thought you had to save them as jpeg so they could print them. Can I also give them Tiff files to print?

[lscottpht]

Don't know the answer to that question as I never use them. Scott??

Wolf accepts jpeg or tiff format.

Costco accepts jpeg or bmp bitmaps.

Another thing we were told is to save in pdf. I don't know anything about that, but that's what we were told.

I only shoot jpg and use wolf for printing. the biggest I print is 8x10 and my prints are excelent from wolf. I think they recently changed printing color profiles (or something) as I use another online place for when I need higher quality and better color prints, and the wolf print matched my other places print perfectly.

Hi Leslie,

PDF? Reallly? I've actually never heard that advice and am interested why someone would want to do that. The only reason I can think of is that it's a cross-platform compatible format and easy to distribute so if it were for sharing reasons, I guess I could see it.

Are there any reasons pertaining to color? Does it maintain a specific color profile?

I understand the issues with JPG, TIFF, PSD, DNG and RAW but never head the PDF one before.

Hmmm...

Oh, sorry, I'm not very technically apt when it comes to this digital stuff. I think I meant psd.

save a photo image in pdf? an adobe acrobat file format? I never heard that before. or was it a psd file format?

[Joe_Lorenzini]

PSD makes more sense but I'd still caution against using this format for anything other than sending to your marketing department or a professional printing service.

I certainly wouldn't use it for archival purposes. Too many compatibility issues (future) and I don't really see any advantage over TIFF as far as quality goes.

I'd enjoy hearing a differing opinion,

Thanks for all the replies. I am just starting to shoot in raw and I'll try to be better about saving in tiff. I guess I better get a dvd burner to start archiving.
